The radially wound Vee wire screens, have a tolerance on a 50micron slot of better than +/-15/20microns, with a typical standard deviation of 9micron.
Slot width of 50micron would give a typical open area of 4.5% whilst at 75micron slot width open area is approximately 7.5%.
Direction of normal flow is from inside of the element to outside.
Burst pressure is nominally 50 bars.
Collapse pressure is typically 80 bars.
Smallest outside diameter available at present is 45mm.
A typical length is 1100mm, but longer elements are available.
End fittings can be supplied in line with your specific requirements.
Johnson Screens can calculate and validate performance parameters.
